实验8 SmartLink&MonitorLink

实验任务一：配置Smart Link

  1. 建立物理连接

  2. 基本配置
    [SWD]vlan 10
    [SWD]int rang ge 1/0/1 to ge 1/0/2
    [SWD-if-range]undo stp enable
    [SWD-if-range]port link-type trunk
    [SWD-if-range]port trunk permit vlan all
    SWA,SWB,SWC都进行如上操作

  3. 配置Smart Link
    //创建Smart Link组1，配置其保护VLAN 0 32实例。
    [SWC]smart-link group 1
    [SWC-smlk-group1]protected-vlan reference-instance 0 to 32
    [SWC-smlk-group1]port GigabitEthernet 1/0/1 primary
    [SWC-smlk-group1]port GigabitEthernet 1/0/2 secondary

实验过程出现的问题：没有关闭以下功能。
[SWC-smlk-group1]port GigabitEthernet 1/0/1 primary
The port is an RRPP, STP or ERPS port.

[SWC-smlk-group1]flush enable control-vlan 1//Smart Link组1使能发送Flush报文功能

[SWA-smlk-group1]int rang ge 1/0/1 to ge 1/0/2
[SWA-if-range]smart-link flush enable control-vlan 1
[SWB-smlk-group1]int rang ge 1/0/1 to ge 1/0/2
[SWB-if-range]smart-link flush enable control-vlan 1
[SWD-smlk-group1]int rang ge 1/0/1 to ge 1/0/2
[SWD-if-range]smart-link flush enable control-vlan 1

实验任务二：配置Smart Link&Monitor Link

  1. 建立物理连接
    Smart-link组配置和实验任务一一样。
    2.配置monitor-link组
    [SWA]monitor-link group 1
    [SWA-mtlk-group1]port GigabitEthernet 1/0/1 uplink
    [SWA-mtlk-group1]port GigabitEthernet 1/0/2 downlink

[SWB]monitor-link group 1
[SWB-mtlk-group1]port GigabitEthernet 1/0/1 uplink
[SWB-mtlk-group1]port GigabitEthernet 1/0/2 downlink

查看smart-link组monitor-link组

注：不同smartlink组需要配置不同的控制VLAN，且保证控制VLAN存在，smart link组的端口允许控制VLAN的报文通过。
